> > How will optical size be handled on macOS outside the browser > > Sorry, I don't understand the question. App authors specify font size in points, and we render it at the appropriate size in points. There doesn't seem to be any inconsistency here. This is exactly my point (pun not intended): As you describe, other apps will specify font size in points, thus opsz will be set to that same value. The app rendering 12pt text will do so with opsz=12. But, in the browser, a document that specifies `font-size: 12pt` will render with opsz=16. Thus, if you open a number of apps - Word, Pages, Text Edit, and Safari, with documents that specify 12pt in the documents coordinate system, and render at 100% zoom, Safari will render with opsz=16 and all others will use opsz=12. Safari will be inconsistent with everything else. Your argument rests on the principle that internal consistency is paramount over all other issues (including cross-platform). My assertion is that Safari as implemented is already inconsistent from the point of view of the units that customers use in the documents they create. My assertion may be wrong, and if so I would happy to learn from my error. -- GitHub Notification of comment by robmck-ms Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/4430#issuecomment-549939130 using your GitHub account
